Building #31 is the Fred Sauer House, 314 Old McHenry Road. Fred Sauer was a carpenter and built this house for his family in 1873. The original part is the two-story section. Fred learned his trade helping to rebuild Chicago after the great Chicago Fire of 1871. Note the distinctive medallion in the peak – you'll also see this in several other buildings – a distinctive feature of homes built in the mid-19th century. Remaining where you are, simply look across the street for building #19 and press NEXT STOP.
